Air quality today
The air quality in Amstetten, Lower Austria is currently classified as Moderate. The primary pollutant measured is PM2.5. Four valid measurements were recorded today. The reported PM2.5 concentration is 18.6 µg/m³, while PM10 is measured at 24.0 µg/m³. These values are expressed in micrograms per cubic meter. The PM2.5 value of 18.6 µg/m³ aligns with the reference measurement used for assessment. The PM10 reading of 24.0 µg/m³ matches the reference level for that pollutant. The moderate classification reflects the combined assessment of the available pollutants. The dataset includes four valid observations, providing a basis for the current rating. All measurements correspond to the same sampling period, and no additional pollutants exceed their reference values at this time.
Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Amstetten air‑quality feed contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). The data set comprises 13 individual rows collected from two monitoring stations in the city. For four of the pollutants (NO₂, O₃, PM₁₀ and PM₂.₅) the most recent values were recorded on 2026‑02‑10 at 20:00 UTC, which places them in the “updated within three days” freshness category. The NO record is older, with its latest entry dated 2024‑03‑11 at 11:00 UTC. Overall, nine rows are classified as old while four are recent, indicating that a substantial portion of the historical record is not current.
Across the recent measurements the observed ranges vary by pollutant. NO₂ values span from 14.44 µg/m³ to 16.00 µg/m³, with a median of 15.39 µg/m³, showing a relatively tight band. O₃ ranges from 30.53 µg/m³ up to 39.00 µg/m³ and centers around a median of 34.02 µg/m³, reflecting a moderate spread. PM₁₀ exhibits a broader interval, from 6.00 µg/m³ to 24.00 µg/m³, with a median of 13.50 µg/m³, while PM₂.₅ sits between 18.60 µg/m³ and 23.70 µg/m³, median 21.15 µg/m³. NO shows the widest relative variation for its low concentration range, from 2.43 µg/m³ to 8.36 µg/m³ with a median of 5.39 µg/m³. The dataset therefore provides a recent snapshot for most pollutants but includes an older NO record and a majority of rows that are not up‑to‑date, meaning that conditions in Amstetten can differ across locations and times beyond what the current data capture.
